Abstract: ABSTRACT OF THE DISCLOSURE   The invention relates to a method of forming a pre-stressed concrete member in which at least a bonding surface of a pre-cast con-crete shell has the hydration process therein temporarily arrested by means of heat applied thereto such that reactivation of the hydra-tion process after the stressing of the shell and prior to the pouring into the shell of infilling concrete, results in a strong bond being formed between the bonding surface of the pre-cast concrete element and the infill-ing concrete.  The construction joints bet-ween the infilling concrete and the pre-cast concrete shell are thus of an improved integrity.

Abstract: ELECTRONIC PHONOGRAPH SELECTOR AND MEMORY SYSTEM     Abstract of the Disclosure The embodiment of the invention disclosed herein is directed to an electronic phonograph selector and memory system which enables the selection of records to be played after the proper amount of credits have been accumulated in a coin accumulating circuit.  The system has a movable record carriage for placing a desired one of a plurality of records at a playing location.  The record carriage is transported by receiving a drive signal indicating that a new carriage posi-tion is required.  The code signal information is compared so that when the carriage is at its desired location the search signal is removed.  The movable carriage has a position encoder so that binary code signal information corresponding to the various positions of the carriage can be detected and compared to the codes stored in a random access memory circuit.

Abstract: PROGRAMMABLE SOLID STATE CONTROL FOR MACHINE           TOOL OR PROCESS CONTROL SYSTEMS                 Abstract of the Disclosure A programmable signal processor having solid state compon-ents which can be programmed to duplicate the control functions of an electromechanical relay panel.  The processor includes an AND memory matrix having a plurality of individual inputs and outputs which are connectible through diodes to outputs of solid state gated input memories and through jumpers to inputs of solid state gated feedback memories.  The input memories have inputs which are switched by external inputs to the pro-cessor.  The feedback memories are switched by outputs of the AND memory and provide input signals to the AND memory which simulate the signals provided by normally closed and normally open contacts of a relay.  The outputs of the AND memory are selectively connected through wire jumpers to the inputs of the feedback memories and circuits which control the outputs of the processor so the feedback memories and output circuits of the processor will switch in response to outputs from the memory in an OR logic manner.  The combination of the AND logic functions provided by the AND memory and the OR logic functions provided by the Jumpers permits the processor to be programmed using Boolean logic equations or directly pro-grammed from a conventional relay schematic or ladder diagram without using special programming language.  A two phase clock provides output signals which causes all of the input memories to switch simultaneously in response to changes in the exter-nal inputs to the processor to eliminate races between the switching of the input memories.  The clock also causes all of the feedback memories to switch simultaneously in response to changes in the outputs of the AND memory to eliminate races between the instants of switching of the feedback memories.     The instants of switching of the input memories and the feedback memories are out of phase to eliminate races between the input signals and the feedback signals within the processor and the processor to operate with greater noise immunity.

Abstract: A FRONT DRIVE CARTRIDGE-TAPE PLAYER SYSTEM               WITH FAST FORWARD AND REVERSE MODES                          ABSTRACT    A reversible continuous loop cartridge includes a conventional front accessible pressure roller drive.  A first pulley is affixed to, and rotatable with the roller. A second pulley is coupled through a one way clutch to the cartridge hub.  An "O" ring interlocks the two pulleys, whose diameters are in a predetermined ratio.  When driven in the forward direction the roller, and pulley rotate but the clutch decouples the hub whereby the tape is driven in the well known manner.  When reversely driven the clutch engages such that the roller, pulleys, and hub rotate.  The hub drive assures proper reverse operation of the continuous loop tape.    A fast forward cartridge tape player includes the conventional cartridge receiving cavity and cylindrical capstan.  The capstan is rotatably driven about its verti-cally positioned longitudinal axis by a motor actuated flywheel, and it is located to forcibly engage the cartridge pressure roller on cartridge insertion into the cavity.          Crescents, having a concave face, a convex face, and a vertical dimension are positioned to rotate about the cap-stan.  The concave face encircles greater than 180° of the capstan circumference while revealing a substantial arc on the capstan surface.  The convex face is of predetermined curvature providing a desired fast forward speed/normal speed ratio.  The vertical dimension of each crescent is fixed to allow each crescent access to the pressure roller.     In the normal mode play a means decouples capstan rotation from the crescents and aligns the crescents to allow the pressure roller access to the revealed capstan surface.  In the fast forward mode the crescents are sequen-tially rotatably locked to the capstan whereby, when viewed from above in a plane perpendicular to the longitudinal axis the convex faces form a substantially circular configuration about the capstan thereby effectively increasing the capstan diameter and driving the pressure roller at an increased speed.  Also, the increased capstan diameter forces the cartridge away from the heads and guides in the tape player, thus avoiding deleterious wear between cartridge tape and player components during the fast forward mode.
